Q1. If is the value of integral
using n-segment Trapezoidal rule, a better estimate of the integral can be found using Richardson’s extrapolation as
Q2. The estimate of an integral of
is given as 1860.9 using 1-segment Trapezoidal rule.
Given f(7)=20.27, f(11)=45.125, and f(14)=82.23, the value of the integral using 2-segment Trapezoidal rule would most nearly be 787.32 1072.0 1144.9 1291.5
Q3. The value of an integral
given using 1, 2, and 4 segments Trapezoidal rule is given as 5.3460, 2.7708, and 1.7536, respectively. The best estimate of the integral you can find using Romberg integration is most nearly
1.3355
1.4145 Q4. Without using the formula for one-segment Trapezoidal rule for
estimating the true error, can be found directly as well as exactly by using the formula ,
Q5. For , the true error, in one-segment Trapezoidal rule is given by , . The value of for the integral is most nearly 2.7998 4.8500 4.9601 5.0327
Q6. Given the velocity vs. time data for a body
The best estimate for distance covered between 2s and 10s by using Romberg rule based on Trapezoidal rule results would be 33.456 m 36.877 m 37.251 m 81.350 m
